SIDEWALK-BOX COVER.

Specification of Letters Patent.

Application filed August 9, 1911.

Patented J une 18, 1912.

Serial No. 643,203.

To all 'whom 'it may concern:

Be it known that I, MAnsI-IALL SAUGEDO, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Improvement in Sidewalk- BoxCovers, of which the following is a specification.

This invention relates to a side walk box cover, and the Object of theinvention is to prevent the removal of the cover from such boxes bychildren, or by other unauthorized parties.

The invention consists of a 'cover which can be readily locked inposition by means of a key of a particular construction, in combinationwith a suitably constructed box cover and the said key is presumed to beheld in the possession of the adjoining property owner, or to be held bythe agent of the corporation owning the water or gas mains to which saidboxes lead.

In the accompanying drawings, Figure 1 is a plan view of the device.Fig. 2 is an inverted plan view of the cover. Fig. 3 is a section on theline 3-3 of Fg. 1, showing the position of the key for the purpose ofunlocking the cover. Fig. 4 is a Similar section showing the position ofthe key for the purpose .of looking the cover.

In these drawings 1 represents the upper portion of the box, which boxis provided with a circular removable perforated cover portion 2. Itwill be understood however that the shape of the cover 2 and theperforations are not essential to the invention, but are merely parts ofthe preferred form of construction. This cover is provided with a radialslot 3, and also with an oblong slot 4, which is parallel to it andadjacent the opposite side or margin of the cover. These slots are theonly portions of the invention which appear upon the outside. Theinterior of the box carriesupon its top a circular flange 5, whichflange is cut as shown at 6, said cut portion being in alinement withthe adjacent slots 3 and 4: respectively. At the end of the radial slot3 a lug 7 is formed upon the under face of the cover and engages theadjacent cut out portion 6 of the flange. Upon the opposite side of thecover, and also upon the under face of the cover is a guide way 8, inwhich slides the body portion of a wedge shaped bolt 9,

the outer end of which is provided with a transverse head 10. This boltis adapted to pass through the other cut outportion 6 of the flange 5,opposite that portion engaged by the lug 7, and the said bolt and lugtogether lock the cover in place. The key consists of a suitable handle11 provided with a curved member 12, a shoulder 13 opposite the point ofthe hook, and a stop 14 upon the rear curved face of the hook menber.

To unlock the cover the hook member is inserted in the slot L with thepoint of the hook bearing upon the head 10 of the bolt and theshoulderbearing upon the cover. The handle is then drawn in the directonof the arrow (Fig. 3) until the stop 14 engages the cover. This willcause the bolt to slide in the guide way 8 a suflicient distance todisengage it from the top of the box withdrawing it from the cut outportion 6 of the flange 4:.

To lock the cover in position the key is inserted in the slot 3 andmoved in the opposite directon. This causes the bolt to move back alongthe guide way 8 and through the adjacent cut out portion 6 of the flange5 and the cover is again locked upon the box.

What I claim is 1. The combination with a box, a cover for said box,said cover being provided with two ofl'set slots, a guide way carried bythe under side of the cover, a bolt slidable in the guide way andadapted to be moved in one directon to engage a portion of the box, anda key adapted when inserted in one slot to move the bolt in one directonand when inserted in the other slot to move the bolt in the otherdirecton.

2. The combination with a box having a cut out top portion, a coveradapted to close said cut out portion, said cover having slots adjacentits opposite margins, a guide way in alinement with one o-f said slots,a bolt slidable in said guide way and adapted to engage the under sideof the box top, a transverse head carried by the bolt and -lying betweensaid slots, and a key adapted to be inserted through said slots toengage respectively opposite sides of said head.
